2-Stage Standard Gas Radiant Tube Heaters (MTA)-Image

Solaronics True Dual Aluminized Two-Stage Gas-Fired Infrared Radiant Tube Heaters provide precise air to gas ratios at both the high- and low-heat stages for optimum efficiency. Excessive overheating is prevented and a softer, more stable and comfortable environment is maintained. Can save up to 75% in energy costs over conventional warm air systems, and typically save 10-15% over a single-stage tube heater.

True Dual Aluminized heaters use aluminized steel heat exchangers to resist corrosion. Models available with high-stage gas inputs from 85,000 to 200,000 BTU/hour and radiant tube lengths from 20 to 70 feet. The two-stage gas valve provides a 30 percent differential between the high and the low stage. Heater controls are isolated from combustion air for their protection.

Infrared radiant heat is absorbed by the floor and other objects in view of the heater's heat exchanger, and is not absorbed by the air. This allows use of a lower thermostat setting yet increases personal comfort when compared with forced air heat so that money is saved on the heating bill. The energy efficiency of these heaters makes them a good choice for a green building.

True Dual Aluminized heaters energy efficiency and safety make them an excellent choice for heating commercial, industrial and agricultural buildings.
